Curcumin, a known inhibitor of NF-kB, has been shown to decrease NF-kB activation in human participants. In a recent study, 8 grams of curcumin by mouth daily for 8 weeks was well tolerated in patients with pancreatic cancer and other pre-malignant conditions with no associated toxicities (6, 8). Although there is concern over the body's absorption of curcumin, the bioavailability of curcumin in the study of pancreatic cancer patients was shown, with peak drug levels at 22 to 41ng/mL that remained relatively constant over the first 4 weeks of treatment with 8 grams of curcumin daily (8). Clinical trials with daily dosages of 1,125 to 2,500mg have also confirmed the safety of curcumin and also shown its ability to decrease inflammation in patients with rheumatoid arthritis and in post-operative patients (6, 33, 34). In vivo murine models of chronic fatigue syndrome have also shown that curcumin may also alleviate symptoms of fatigue (35). While these studies are promising, very little is known about the capacity of Meriva to inhibit NF-kB in women treated for BrCA. We hypothesize that oral Meriva, a known inhibitor of NF-kB, may be used to decrease levels of NF-kB activity in BrCA patients previously treated with chemotherapy who go on to receive radiotherapy (XRT), a carefully chosen group of patients at particular risk for high levels of NF-kB DNA binding (a direct measure of NF-kB pathway activity).
